Iodine trifluoride dioxide is an inorganic compound of iodine, fluorine, and oxygen with the chemical formula IO2F3.[1][2][3] The compound was first obtained by Engelbrecht and Petersy in 1969.[4]
Synthesis[edit]
Iodine trifluoride dioxide may be formed by the reaction of HOIOF4 and oleum.[4]
Physical properties[edit]
Iodine trifluoride dioxide forms yellow crystals, which melt at 41 °C.[5] Decomposes under direct sunlight or heating.
The molecules in the crystals are dimers. The compound is monomeric above 100 °C.[6]
Chemical properties[edit]
Iodine trifluoride dioxide decomposes when heated:
- 2IO2F3 → 2IOF3 + O2
